`IMPROVEMENT IN GAS-BURNERSA.

Specification forming part of Letters Patent N0. 39,820, dated September 8, 1863.

To all 'whom it may concern.-

Be it known that I, FREDERIK LIINKEN- HEIMER, ot' the city of Cincinnati, in the county of Hamilton, in the State of Ohio, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare that the following is a full and exact description thereof, reference being had -to the accompanying drawings, and to the letters of reference marked thereon.

The nature of lny invention consists in constructing a gasburner in such a manner that the gas, in passing` through it, shall be spread out into thin annular layers, and otherwise attenuated or wire-drawn, while at the same time it shall be detained for Aa considerable time in the burner, exposed to the heated surfaces composing it, and thus the temperature otl the gas raised to a high degree before escaping.

Another important feature of my invention consists in a simple and efficient arrangement by which 1t may be adjusted so as to afford any required amount ot gas, while at the saine time, owing to the circnitous direction given to it, there will not be any b'owing or waste of gas arlsing from different pressures in the mains.

'.Io enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The general external appearance of my burner is similar to the ordinary burner.

Figure 1 is a section through the center of the burner ot' the ordinary or common size. Fig. 2 is a similar section enlarged to twice the common size, in which the tip D and the female screwj at the bottom are omitted; `and Fig. Sis a plan through a a, Fig. 2.

The saine letters represent the same things in all the Iigures.

My burner is composed of three pieces. The tip D may be of any desirtd pattern. A is the outer case or cap, into which the tip I) is screwed. It is attached to the main socket or tube B by means of the screw shown at h h. This socket B is screwed upon the-end of the service or bracket pipe by the female screw at j, Fig. l, and upon it the inner hood or cap, C, is secured by means of the screw shown at t', Figs. l and 2. When put together ready for use, they form the burner, as shown in Fig. 1, in which E is the cylindrical tube through which the gas is admitted, and from which it passes, through the openings F F F, Figs. 2 and 3, (of which there may be any convenient number-usually two or four,) into the annularchamberGr G, Figs. 2 and 3, and along this to the valve g g, Fig. 2, which valve consists ofthe conical portion ot B, as a seat, and the concave cone formed by the lower end of the inner hood or cap, C, as a valve, thence along the outer annular opening or chamber H H, Figs. 2 and 3, and thence into the tube I of the tip D, Fig. I, and so out, as indicated by the lines or darts in red in Figs. 2 and 3. The amount of gas is regulated by turning the inner hood or cap, C, up or down on the screw i, thus enlarging or diminishing the opening at g g at pleasure.

It is manifest, from what I have said, and an inspection ot the several gures, especially Fig. 3, that the several parts are cylindrical in form.

The gas, in passing through this burner, as above described, is spread out into thin cylindrical tubes, as shown in section at H and G, Fig. 3, and while in this form is retained for a considerable length ottime in contact with the heated surfaces ofthe several tubes A, B, and C, thus heating it to a high temperature, while by the eircuitous route it is made to traverse, together with the adjustable valve g g, all blowing is avoided, and a very perfeet combustion and large yield ot` light afforded.

The conical form of the regulatingvalve, the absence of contracted openings in which impurities may lodge, the ease and readiness with which it may be adjusted and cleaned may be mentioned as among its advantages over all other adjustable burners.

I am aware that the adjustable burner is not new. others having invented various devices tor eftectin g that object; nor do I claim that retarding or retaining the gas ,in the burner, tor the purposes ot' producing steadiness of iow and heating the gas, is new or my invention; but

What I do claim, and for which I desire t obtain Letters Patent, is v rIhe conical adjustable valve g g1, Fig. 2, i combination with the cap or hood (U, with the screw t', the openings F F F, the tubes H H and G Gr, for the purpose of regulating the now ot' the gas, substantially as set forth and described.
